Ever since the seventh, current console generation began in 2005 with the release of the Xbox 360 and continued into 2006 with the simultaneous launch of the PlayStation 3 and Wii, each console has been more-or-less defined by its target demographic, with the Xbox and PS3 skewing for older audiences and "hardcore" players and the Wii being partial towards "casual" players. That being said, there's a lot of overlap. The Xbox and PS3 have their fair share of "casual" games, and the Wii in turn has plenty of games made for the "core gamer". All of this begs an interesting question: Is it the designer's obligation to design their work for a particular demographic? Or can they design something for a "general audience"? To both questions, I say yes and no. A designer shouldn't try to please everyone because they simply can't. There's always going to be people who don't like something. On the other hand, it's also not a very good idea to go after one specific demographic and shut everyone else out. When all is said and done, it's a balancing act. The true challenge of any designer is to combine breadth with depth. The challenge is to not only get a general audience interested in your work, but also to get as many people as you can invested in it for as long as possible.
